Singular point of a curve

In geometry, a singular point on a curve is one where the curve is not given by a smooth embedding of a parameter. The precise definition of a singular point depends on the type of curve being studied. (Wikipedia).

C72 What to do about the singular point

Now that we can calculate a solution at analytical points, what can we do about singular points. It turns out, not all singular points are created equal. The regular and irregular singular point.

Algebraic geometry 37: Singular points (replacement video))

This lecture is part of an online algebraic geometry course, based on chapter I of "Algebraic geometry" by Hartshorne. It defines singular points and tangents spaces, and shows that the set of nonsingular points of a variety is open and dense. This is a replacement for the original video,

algebraic geometry 34 Blowing up a point

This lecture is part of an online algebraic geometry course, based on chapter I of "Algebraic geometry" by Hartshorne. It covers blowing up a point of affine space, and gives some examples of using this to resolve singularities of plane curves.
